Sequence categories for all HLA-A, B, C, DPA1, DPB1, DQA1, DQB1, DRB1, DRB3, DRB4, and DRB5 alleles in IMGT/HLA Database release 3.2.0 are color coded. Known sequences are shown in green, unknown sequences that are 5′ of the peptide binding domain (PBD) encoding exons (exons 2 and 3 for class I, and exon 2 for class II alleles) are shown in blue, imputed sequences that are 5′ of the PBD exons are shown in red, imputed sequences that are 3′ of the PBD exons are shown in purple, and unknown sequences that are 3′ of the PBD exons are shown in aqua. The horizontal scale indicates the distance in nucleotide bases from the start codon.
A. Sequence categories for 4268 class I alleles over exons 1-8.
B. Sequence categories for 1248 class II alleles over exons 1-6.
